The cam when in one par sition pcrinittingir the husp to raise and when in another position, at an angle of about 90 from its liist position, causing' tbe hasp to be moved downwmfdlyto disengnge .its shoulder .from tbe opening' in tbe doo?.A catch. This com is provided on one sido it a point dinnletiioally opposite its curved coin face 24 with o. proie tion v5 on opposite sides of which sliouldcle LPG- 2T are formed.
